基于网格模型的三维人体自动化测量方法

摘要

面对大量的人体精确尺寸测量的客观需求,本文构建了一套完整的基于网格模型的人体自动化测量方法.该方法首先对点云进行自动化建模生成网格模型,然后提出并采用一种切割方向和切割厚度均自适应切片对网格模型进行处理得到一系列二维截面,再采用截面间围堵分析和截面内凹凸性分析的方法自动找到了人体特征界标,最后分别采用真实男性和女性塑料模型进行了精度和重复性试验,结果表明本文方法效果良好.%In the face of a large number of accurate measurement of human body, a complete automatic measurement method based on mesh model is constructed in this paper. Firstly, The point cloud is modeled to generate the mesh model. Secondly, a cutting direction and slice thickness adaptive slicing are proposed to deal with the mesh model, and a series of two-dimensional cross sections are obtained. Thirdly, the analysis method of convex analysis and cross section within the containment section automatically find the characteristics of the human body landmarks. Finally, the accuracy and repeatability of real male model and female mode are tested, and the results show that the method is effective.
